Abstract(in English) | Our research objective is to classify magnified endoscopic images of colorectal tumours into 3 types (Type A, B, and C3) based on NBI magnification findings. In this technical report, we propose a system for classifying colorectal endoscopic images. These types are classified by pit and microvessel structure of colorectal mucosa, and have a strong correlation with histologic diagnosis: hyperplasias (HP), tubular adenomas (TA), and carcinomas with massive submucosal invasion (sm-m). A dataset of 908 NBI images are classified by using a SVM classifier with densely sampled SIFT descriptors, and a rate of 96.00% with 10-fold cross validation was achieved. |
